ShadeMart 17ft x 23ft White Sun Shade Sail UPF50 Rectangle - Heavy

In this review the ShadeMart 17' x 23' white rectangle shade sail is evaluated for homeowners and small-business owners who want broad, breathable sun protection without a solid roof. The bottom line: it delivers durable UV protection and cooler outdoor space in an easy-to-install fabric form. The sail is made from woven HDPE with stainless steel D rings and heavy webbing, and it blocks up to 95% of harmful UV rays while remaining water permeable, making it a practical choice for patios, carports and poolside shade.

Key Features

• Woven HDPE fabric: the material is breathable and lets air pass through so the shaded area stays cooler without trapping heat.
• UPF50 sun protection: blocks up to 95% of harmful UV rays to reduce sun exposure and lower ambient temperature by about 10 to 15 degrees.
• Stainless steel D rings: rust-resistant corner hardware is attached to heavy white webbing for reliable anchor points in outdoor conditions.
• Water permeable: the sail lets rainwater pass through rather than pooling, which protects the fabric and reduces strain on attachments.
• Custom sizing available: multiple sizes and custom options let you order a fit for patios, carports, pergolas or pool areas when precise measurement is required.

Who It's For

This shade sail is best for homeowners, renters with outdoor living space, and small businesses that need an affordable, semi-permanent canopy to cool porches, patios, carports and pool areas. It works well where airflow and UV protection are priorities and a waterproof roof is not required.

People who need complete rain protection or a rigid canopy should look elsewhere; this style is explicitly not waterproof. Also, buyers who cannot take accurate measurements should consider professional measuring or a simpler pre-measured option because custom sizing depends on correct venue dimensions.

Pros & Cons

Pros

• Durable woven HDPE fabric provides long-lasting UV resistance and holds up well in sun exposure.
• Stainless steel D rings and heavy webbing improve attachment reliability and durability.
• Breathable, water-permeable design keeps the shaded area cooler without pooling water.

Cons

• Not waterproof, so it will not protect against heavy rain or serve as a replacement for a solid roof.
• Size accuracy depends on manual measurements and some customers report mixed results on sizing fit.
